The easiest way (and I'm sure others will recommend this too) is to use
HTML::FillInForm.
The next best way (IMHO) is to do a simple variation of your second
method:
perl:
$tmpl->param( $q->param('Color')."_Checked" => "checked");
template:
<input type="radio" name="Color" value="Red" <!--TMPL_VAR
NAME=Red_Checked -->">
<input type="radio" name="Color" value="Blue" <!--TMPL_VAR NAME=Blue_Checked -->">
